The mohod of adding the enter channel to the rear speaker works
as follows:

1. You need to get the rear speaker signals at line level outputs
   (directly use those outputs if thye exist, otherwise convert from speaker
   level)

2. Connect those line level rear speaker signals to left and right inputs
   of the surround amplifier. Left rear left and right rear right.

3. Connect the rear speakers to left and right main speaker outputs of
   the surround amplifier. Connect the center rear spaker to the center
   channel outputs.

4. Set the amplifier to "Dolby 3 stereo" mode

And now you have the syustem set up. All you have to do after
this is to adjust the volume levels of your system so that all
rear spakers match the front speakers.
